Non-Members Can Post
This setting indicates that people who are not members of this mailing list will be allowed to post.
The default setting is "NO" that means that if someone tries to contribute a message to this mailing list, and their email address is not listed as a member of the list, their message will
automatically be rejected.
A setting of "YES" means that the person's contribution will not be rejected. However, if the list is moderated in some way (either full or number moderation) their message will be put of for
moderator approval. For example, if your list is set to number moderate, so that new members need their first message approved, any message coming from a non-member will be treated as if a new
member posted it, and will require moderator approval.
Please note that allowing non-members to post, and not having moderation means that anyone can send email to your list address, and it will be distributed to your members.
